Go with the 34. It flows more air for cheaper than the 39 is going to be.

But you have already asked the guys on wrxfanatics and x and Jeremy really know thier stuff so listen to them...i would.

It true that I ask this question on WRXfanatics forum but a forum it's for what??? And your right when you talkingg about Jeremy and X , Both they are very nice guys!!
In new turbo maybe the VF34 is cheaper but I bought my kit used and I saved a lot of bucks.
And you, what do you have on your rex??? TD04??

And I saw a friend with 287whp/281wtq with his VF39 ported at 17psi....

I must upgrade all the Other aspects of the vehicle before the turbo because what good is it to go fast if you can't stop. If you got a good deal on the 39 thats peachy I was only trying to help you out so thanks for being a prick.

Actually no I have and XT with .5 more displacement and will kick you cars azz stock for stock. Before you run your mouth know what you are talking aboot.

Per NUMEROUS threads (which can easily be found)...

IHI VF 24/28/29 ----- 410 CFM at 14.7 PSI <--- estimated
IHI VF 24/28/29 ----- 425 CFM at 18 PSI <--- estimated

Still looking for a solid answer on this. I see the ~450 up top, but another very detailed (but hard to follow due to technical nature) thread I found while using google seemed to say 490 CFM. That being said, has it been confirmed how much CFM a stock-spec VF39 puts out? (or what it could be rated as compared with other turbos?)

That is so much crap. The VF34 is way more expensive and you get about the same amount of power out of it. I may spool a bit quicker but by about 100 - 150 rpm due to the roller bearing.
I think it is around the 450 region though.

It's kinda funny, cause I looked in the 2.5 forum too. Still, no definitive info on how many CFM of air the VF39 pushes out.

^^ ok.
That is true becasue they both use the P18 Exhaust housing, but the roller bearing over the VF39's thrust bearing, which is why it spools qucker.
